The Truth About Carbs
String together a bunch of simple carbs, and you get these larger molecules. Your body has to break them down into simple carbohydrates and then into glucose before it can use them. This takes longer, which means your blood sugar goes up more slowly and they’re less likely to be changed into fat. These kinds of carbs include multigrain breads and pasta, beans, potatoes, and other vegetables.

What Are Carbs?

They’re one of three types of food that give your body energy. The other two are proteins and fats. Together, they provide the fuel your body uses to build and repair itself. Carbs break down into glucose (sugar) that you can use right away.

Your Body’s Fuel

Your body runs on glucose. Your brain, in particular, needs it to work the way it should. Carbohydrates are an almost instant source of it. Your body can break down and use fat for some of the same needs, but not all of them. Plus, fat that’s used for fuel makes compounds called ketones that can raise the level of acid in your blood, and that can be unhealthy over the long term.

Full of Nutrients

The best-quality carbs — berries, vegetables, and whole grains — are packed with vitamins, fiber, and antioxidants that are important for good health and well-being. Whole grains have fatty acids, magnesium, B vitamins, folate, and zinc. Fruit and starchy veggies have some of those, plus phytonutrients like flavonoids and carotenoids that help prevent disease. If you skip the carbs, you lose out on those nutrients, too.

Workout Prep

Because carbs are a source of energy, they can keep you going strong while you exercise. Experts recommend fueling up 1 to 3 hours beforehand with a combination of carbs and protein, like oatmeal, Greek yogurt, peanut butter, or nuts and raisins.

Simple Carbs

Think of table sugar as simple carbs in pure form. They’re very small molecules, which makes them especially easy for your body to break down and use. That means they raise your glucose levels (blood sugar) really fast. Things that sweeten any number of candies, pastries, and desserts are loaded with these kinds of carbs.

Complex Carbs

String together a bunch of simple carbs, and you get these larger molecules. Your body has to break them down into simple carbohydrates and then into glucose before it can use them. This takes longer, which means your blood sugar goes up more slowly and they’re less likely to be changed into fat. These kinds of carbs include multigrain breads and pasta, beans, potatoes, and other vegetables. Read more
